INSTALLATION FOR STORAGE AND TRANSPORTATION OF LIQUEFIED GAS Russian patent published in 2022 - IPC F17C13/00 

FIELD: storage; transportation.

SUBSTANCE: group of inventions relates to an installation for storage and transportation of liquefied gas. The installation for storage and transportation of liquefied gas includes bearing structure (1) containing a bearing wall equipped with hole (22, 122), sealed and heat-insulating tank (2) built-in the mentioned bearing structure. The mentioned sealed and heat-insulating tank has a tank wall installed on the inner surface of the bearing wall. The tank wall has one heat-insulating barrier (13, 15) and one sealing membrane (14, 16), which are superimposed on each other in the direction of thickness of the tank wall, as well as sealed metal pipe (7, 107), which is installed in the hole in the bearing wall. Sealed metal casing (29, 129, 52, 152) is located around the pipe. The sealed casing has a longitudinal section extended in parallel to the sealed pipe through the thickness of the heat-insulating barrier to sealing membrane (14, 16). Sealing membrane has a hole, through which the sealed pipe passes, and it is hermetically connected to sealed casing (29, 129, 52, 152) along the entire perimeter of the mentioned hole. The bearing structure contains coaming (24, 124), which protrudes from the upper surface of the bearing wall, and which is located around the sealed pipe, while the sealed pipe is supported by upper wall (26, 126) of the coaming.

EFFECT: provision of a simple structure for passage of a sealed pipe to a sealed and heat-insulating tank of a membrane type.
